Overview
- Kei Nishikori lost in the final round of US Open qualifying to 20-year-old Rei Sakamoto by 4–6, 6–7 and did not reach the tournament’s main draw.
- Nishikori has said this season will be his last, so the qualifying defeat closes his run at this Grand Slam during his announced farewell year.
- Shintaro Mochizuki, who lost in qualifying, was later promoted into the main draw as a lucky loser after a main-draw withdrawal, securing a place despite his loss.
- In the women's qualifying bracket, Sakazume Himeno won her final qualifying match to reach the main draw while Nao Hibino was eliminated.
- Qualifying at the US Open can produce sudden shifts because players who lose can still enter the main draw as lucky losers and surprising young winners can accelerate a generational change.
